MACHINE FOR LINING STRAW AND OTHER BOARDS.

SPECIFICATION forming part of Letters Patent No. 327,404, datedSeptember 29, 1885.

Application filed April 14, 1884. (No model.)

To all whom it may concern.-

Be it known that I, GORDON MUNRO, acitizen of the United States, ofTroy, county of Rensselaer, State of New York, have invented a new anduseful Improvement in Machines for Lining Straw and other Boards, ofwhich the following is a full, clear, and exact description, referencebeing had to the accompanying drawings, making part of thisspecification.

My invention relates to improvements in that class of machines forlining or facing straw board or other board, or cloth or other fabricsin which the paper, muslin, or other flexible lining or facing materialis supplied continuously from a roll of such lining or facing material.

My invention consists of the combination, with a suitable frame providedwith suitable bearing-boxes and projections for carrying or attachingthe several parts, of a deliveringreel suitable for carrying a roll oflining or facing material, suitable devices for guiding the liningorfacing material, and for spreading paste, glue, or other suitableadhesive fluid upon the lower face of the lining or facing material, anda pair of revolving reversing feed-rolls, the axes of which are in thesame vertical or nearly vertical plane the line of contact of thefeed-rolls being at a suitable height above thelevel of thedelivering-reel, the construction and arrangement of the several partsbeing such that when the machine is in operation the lining or facingmaterial passes around a part of the face of the lower feed-roll, and isthereby reversed, having its adhesive face turned uppermost beforeentering between the feed-rolls, where it comes in contact with thematerial to be lined, and is caused to adhere to that material, the twomaterials being pressed together by the re volving feed-rolls while,carried through between the said rolls.

My invention consists, further, of the combination, with a suitableframe provided with suitable bearing-boxes and projections for carryingor attaching the several parts, of a de livering-reel, aspreading-cylinder, an adhesive-fluid box, and a pair of reversingfeedrolls, the spreading-cylinder being so located between thedelivering-reel and the reversing feed-rolls. in or over theadhesive-fluid box,

that when in operation its lower surface is in contact with or a littlebelow the surface of the adhesive fluid contained in the box, and itsupper surface above any straight line that may be drawn from above orbelow the delivering-reel, where the lining material feeds off of thatreel, to the under side of the lower reversing feed-roll, or to theunder side of an intermediate guide-roll, when such a guide-roll isemployed, the line of contact of the reversing feed-rolls being at asuitable height'above the roll of lining material and the spreadingcylinder, the details of construction and ar rangernent being such thatif a roll of the lining material be placed upon the deliveringreel andthe end passed over the spreadingcylinder and around the under side ofthe lower reversing feed-roll, and in between the two feed-rolls, andpower he applied to the lower feed-roll, causing it to revolve in the.proper direction, the lining material will unwind from the roll, pressupon and revolve the spreading-cylinder, receive on its lower surfacethe adhesive fluid, and pass below the lower feed-roll, and in betweenthat roll and the upper feed-roll, with the adhesive surface uppermost,in such manner that the material to be lined or faced entering with andabove the lining or facing material, the two inate- The drawingsrepresent a straW-board-lining machine embodying my invention.

Figure 1 is part longitudinal section, part elevation, of' such amachine and feed-table. Fig. 2 is a plan of same. Fig. 4 is a plan ofthe adhesive-fluid box. Figs. 3, 5, 6, 7, 8, and 9 are details. l

A is the fran1e,having slotted projections a, b, and c for carrying thejournals of the re spective rolls. (1 is a suitable bearing-box of thedelivering-reel B. The reel B is asimple axle with collars, or may beconstructed in any manner suitable for carrying the roll e of liningpaper. G is the spreading cylinder,

- LII which should be as light as possible, well balanced, and revolveeasily. I prefer to have it well made of sheet-tin, with a light steelor iron axle revolving on the conical points of screwsf at either end,as shown in Fig. 5.

D is the adhesive-fluid box, which, for con venience in cleaning, isremovable, simply resting when in use upon the longitudinal bars 1 ofthe frame A. The box D carries the guide-roll h, the scraper t, and theequalizingroll j, when, as in the example shown in the drawings, thesaid guide roll, scraper, or equalizing-roll are employed.

Rolls h and j, like cylinder 0, revolve on the conical points of screwsf, passing through nuts 7c in the ends of box D, and may be secured byjam-nuts Z. The guide-roll h, by pressing down the paper, increases thesurface of contact between the paper and cylinder 0. The scraper 'i isatransverse rod,over which the paper passes, and by which any excess ofthe adhesive fluid is removed from the under side of the paper. Thepressure of the scraper on the paper is regulated by two ad- 2justing-screws, m, one in each end of the rod,

passing through the enlarged ends of that rod, as through anut, and heldin position by bear ing-boxes n and 0 attached to the ends of box D. Theequalizingroll j serves to equalize the distribution of the adhesivefluid on the lower surface of the lining-paper.

E F are the reversing feedrolls. The endless apron G is carried by thetwo parallel rolls H and I.

J and K are the apron presser-rolls, which press the lined board down onthe apron in passing over the rolls Hand I, the pressure tending tocause the linin gto adhere more one, s, overriding the other, if.

smoothly and evenly to the board than if the reversing feed-rolls E Fwere exclusively employed for that purpose. The axles of the lowerreversing feed-roll, E, and the apron rolls H and I project on one sideof the machine and carry belt-pulleys p, q, and 1'. The upper surface ofthe apron G is on a level with the top of the lower feed-roll, E. Theapron is driven by two belts, s and t, The axle of roll E projects onone side or other of the machine to receive power, as from a beltapplied to the pulley u, or from the hand applied to the crank-handle U.L is a feed-table, the projecting edge M of which is placed as near aspossible to the feed-rolls, the upper surface of the table being on alevel with the top of the lower feed-roll. Upon the upper surface of thetable is a guide, N, working in a suitable transverse guide-slot, O. Theinner or working edge of the guide is placed at asuitable distance fromthe edge of the table to guide the straw-board, and is secured in anydesired position by turning the clampscrew 1?. As the table may be inthe way when it becomes necessary to insert the end of the 1 paperbetween the feed-rolls, the top is hinged at Q by a suitable hinge, Q,and the rear end or edge, M, may be pushed or tilted down. The front endbeing the heavier, the top will regain its horizontal position when leftto itself.

R and R are sheets of straw-board. The lining-paper after it leaves theroll e is indicated by the letter w. It passes over thespreading-cylinder G, the lower part of which is slightly immersed inthe adhesive fluid 00, causes that cylinder to revolve, and receivesfrom it a coating of the fluid. From the cylinder O the lining-paperpasses under the guide'roll h, over the scraper t and equalizingroll j,under and around the lower reversing feed-roll E, in between the twofeed-rolls E F, and back horizontally over the apron and under the apronpresser-rolls J and K, and out at the rear of the machine... Thestraw-board is pushed, sheet after sheet, from the table, guided by theguideNnin between the feedrollers, where the contact with and pressureagainst the adhesive surface of the 1ining-paper causes the board andpaper to adhere to each other and to move on together toward the rear,where each successive board, with its lining, is received and removed byan attendant, who cuts or tears the lining-paper across between theconsecutive sheets of strawboard.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a machine for lining straw-board, the combination, with thedelivering-reel located beneath the table, of the paste-box extendingtransversely across the machine, and provided with bearings for thereception of a pastingroller, and guiding-rollers for regulating thepath of the lining material, also journaled in the side walls of thepaste-box, all located beneath the table, substantially as and for thepurpose specified.

2. In a machine for lining straw-board, the delivering-reel andpaste-box extending transversely across the machine, and located beneaththe table. in combination with a pastingroller, and guiding-rollers forregulating the path of the lining material, said rollers being journaledin the side walls of the paste-box,

and an adjustable scraper-bar, substantially as and for the purposedescribed.

3. In a machine for lining straw-board, the combination of thedelivering-reel B and pastebox D, located beneath the table,paste-roller O, guide-rollers h and j, and scraper t, located withinsaid box, and the reversing feed-rolls E and F, all arranged in themanner substantially as and for the purpose described.

4. The feed-table L, suitable for a strawboard-lining machine, having atilting top with suitable hinges, Q, and the movable guide N,substantially as described and set forth.

In testimony whereof I have hereunto set my hand this 7th day of April,A. D. 1884.
